🏡 Our first completed SigenStor install - on a Passivhaus.
Passivhaus is one of the most demanding build standards in construction. The building fabric does the heavy lifting on heat retention, which means every system inside has to be specified precisely to match.
System Overview:
🔹 Stiebel Eltron HPA-O 05.2 Trend HC 230 Air Source Heat Pump
🔹 Stiebel Eltron SBB 200 HP Trend Hot Water Cylinder
🔹 SigenStor 3-phase 25kW Inverter
🔹 SigenStor 9kWh Battery
🔹 Sigen Energy Gateway
🔹 MVHR completed by Earthwise Construction
The SigenStor system is built for whole-home energy management, 3-phase, 25kW inverter capacity, and genuinely designed to maximise self-sufficiency rather than simply limit export.
This is our first SigenStor project, and we're looking forward to seeing.
